Would it be possible to uninstall SEP and put some other software on there and see how it runs for a while? Basically, we want to try to isolate a particular application or service from the mixture to identify the problem.

I just got back from a cleaning spree on the inside. (Un)fortunately everything was pretty clean in there. I removed and dusted the fans and peripherals and sprayed some air in and around the heatsinks. I reset all the memory and reconnected all the devices.

I'm currently running a Memtest which seems to be going smoothly, so the next step will be get rid of SEP.

yeah these are one of those puzzling things were patience and elimination comes into play alot of times, I would take the users HD and place it into another working system to rule out if its H/W and if it continues then you know you can start looking at the S/W angle!

The PC was hand-built a few years ago, it could definitely be a failing piece of hardware, just not sure which right now.

Jaguar,

It's in a pretty good "test" environment now, the user sits about 10 feet from me and he's on our tech support team, so we are able to keep a keen eye on the system, just looking for more options to test at this point.

If the CPU heatsink is relatively cool, it could still be an overheating issue. have you tried reseating the CPU heatsink with fresh thermal paste? The other thing I would check is the graphics card (if it has one) or the mainboard chipset for the same thing.
